Fourth bit:
Incidentally, we’ve worked with elite athletes who want to fat-adapt — it makes sense because if we’re running on carbs we don’t run for very long. Energy from carbs (stored as glycogen) only lasts about 60 to 90 minutes if we’re exercising vigorously. Our fat stores, meanwhile, amount to 135,000 calories meaning if you’re running an ultra-marathon you don’t need a glucose gel every 60 minutes — you refuel on water and electrolytes and keep going. But you don’t need to be an elite athlete — anyone can fat-adapt.
The ketogenic springboard
Good levels of fat adaptation can be achieved in two to four weeks. It’s uncomplicated, but it isn’t easy. As a springboard into efficient fat-burning you need to adopt a low-carb, high-fat ketogenic diet. (Ketones are alternative fuel for the body when glucose is in short supply — they are produced by the liver from fats).
The important thing is to keep to a maximum of 25-50g of carbs a day. Carbs should be 5 per cent of your diet, fat 70 per cent and protein 25 per cent. Eat three meals a day (sensible for the first month) and don’t snack. You might breakfast on poached eggs, smoked salmon and spinach, a full English, or full-fat Greek yoghurt with berries and macadamia nuts. Lunch might be Greek salad or a cheese omelette. Dinner might be chicken, or cod and chorizo with buttery leeks, or steak with roasted vegetables and cauliflower mash. Carb withdrawal is tough — make sure you’re supported as you prime your body to be a fat-burning machine.
The Diet Whisperer is specifically a plan that resets your metabolism in 12 weeks, and we wrote it to help those who were struggling — but if your hormones are generally behaving with a little room for improvement, you can adopt whichever of its principles suit to improve wellness.
So if your hormones require a significant amount of whispering, we advise minimising starchy carbs for three months before reintroducing them into your diet, but otherwise continue to eat whole, nutritious varied foods, including legumes, beans, lentils, root vegetables and wholegrains such as quinoa and buckwheat throughout. (We can’t overemphasise the importance of enough fibre.)
However, once you hit your target weight, refined carbs such as potatoes and rice can also be a measured part of your diet. Long-term restrictive diets can lead to nutritional deficiencies, so it’s important to eat mindfully and find your own equilibrium — and you can always adjust as necessary. Eat well, be well.

Eating fat makes you fat? It’s a myth
For more than 40 years we’ve been told that fat is bad. Actually, fat is our friend. It’s a great macronutrient. Our bodies need fat — 60 per cent of our brain is fat, cell walls contain fat, for example. The only bad body fat is visceral fat — and high-risk factors for visceral fat include drinking alcohol, consumption of fast-digested carbs, and high-frequency meals.
But eating good fat (within a limited time period each day) promotes health and helps us to lose weight. And fat adaptation — reteaching our body how to burn fat for fuel — is a Whisperer fundamental. It’s just knowing when to eat and what fat to eat.
Good fats fall into four groups — saturated fat (yes indeed), monounsaturated fat, polyunsaturated fat and cholesterol (you read that right too.) The only bad fat — to be avoided — is trans fat, found in processed food, and a killer.
Saturated fat Found in meat, dairy, whole milk, butter, cheese, dark chicken meat, chicken breast skin, lard, and oils such as coconut. These fats do not cause heart disease.
Cholesterol Bad cholesterol comes from a liver damaged by high-sugar diets and fructose. Healthy cholesterol-rich foods include avocados, nuts, eggs, liver, shellfish, oily fish and grass-finished meat such as beef, lamb and venison. As part of the Whisperer lifestyle enjoy a steak, cooked on a cast-iron skillet, dressed with butter, plus buttered greens and mushrooms. (And occasionally have the chips too.)
Monounsaturated fatty acids (MUFAs) Avocados, olives and extra virgin olive oil are rich in these fatty acids. Extra virgin olive oil contains oleic acid, a high intake of which has been linked with reduced insulin resistance. People on the MUFA-rich Mediterranean diet have shown reduced “bad” cholesterol. These fats are also associated with reduced inflammation.
Polyunsaturated fatty acids (PUFAs) These include omega-6, and omega-3. Both are essential and our body can’t make them. But omega-6s are pro-inflammatory, while omega-3s are anti-inflammatory, so it’s vital to consume the right amount of each. Our omega-6 to omega-3 ratio should be four to one or below. Alarmingly, in the average western diet the omega-6 to omega-3 ratio is 50 to one. Combined with speedily digested carbs, this is associated with increased inflammation, increased insulin resistance and increased obesity, to name a few. To improve your 6:3 ratio, eat at least two portions of oily fish a week, such as salmon, sardines, mackerel and anchovies.
Crab has a 6:3 ratio of 1:60. Tinned tuna in water has a 6:3 ratio of 1:30. But in sunflower oil its 6:3 ratio is 13:1. Shellfish are also a good source of omega-3. If you don’t eat fish, take fish oil daily (4-5g for men; 3-4g for women.) For vegetarians there are algae sources such as spirulina and chlorella. Grass-fed meats such as venison have a good 6:3 ratio (grain-fattened meat not so much).
